実験手順
Stage 3.05 g (3.23 mmol) of 4-chloroacetophenone are stirred in 3.6 ml of dimethylformamide diethylacetal for 17.5 h at 110°. After cooling, precipitation is effected with hexane and the precipitate is isolated by filtration and dried. 3-dimethylamino-1(4-chloro-phenyl)-2-propen-1-one is obtained; 1H-NMR (DMSO): 2.9 (3H,s), 3.1 (3H,s), 5.8 (1H,d), 7.5 (2H,m), 7.75 (1H,d), 7.95 (2H,m).
